Greptile Summary

Removes the Slurm benchmark’s conditional system-package installation, leaving Python dependencies to be installed directly with pip.

Confidence Score: 5/5

The PR appears safe to merge with no concrete, changed-code-triggered defect identified.

The change removes node-level package installation while retaining pip dependency setup, and the repository does not establish a supported runtime where this causes dependency installation or benchmark execution to fail.

Important Files Changed

Filename	Overview
slurm/cpu/password-hashing-benchmark.sbatch	Removes the apt-get block for native build dependencies; no concrete failure is established because the target Slurm environment and wheel compatibility are unspecified.
